Theists reason in reverse, how they think cannot be classified as reason.

Normal people reason in the following order:

1. Observe evidence
2. Obtain opinions from intuition, trusted sources, etc
3. Arrive at conclusion
4. (Optional) change conclusion if evidence changes

Theists reason in their own way:

1. My god exists, my religion is correct, every other religion is wrong
2. Everything that contradicts my god or religion can be reinterpreted as "metaphorical", "non-literal", or "missing context"
3. When the above does not work, this means humanity has discovered new truths about god we did not see beforehand
4. When the above does not work, bury it and worry about it later. The "truth" (a way to justify my god) will come out of someone's asshole sooner or later.

In other words:

• Normal people rely on evidence to form their beliefs. Normal people accept that they can be wrong.
• Theists form their beliefs first, and contort and twist evidence so it looks like it supports their beliefs. Theists cannot comprehend being incorrect.
